Excerpts: Single-bubble sonoluminescence (SBSL) has attracted much attention owing to both the apparent simplicity of its creation and the complexity of processes occurring during bubble pulsation. (...) At appropriate acoustic intensities, the bubble can emit short ( 50-500 ps) flashes of light with clock-like regularity. (...) suggested the existence of extraordinary temperatures inside the bubble, with black-body effective temperatures as high as 20,000 K. (...), so SBSL is now generally believed to be due, at least in part, to black-body radiation, bremsstrahlung and ion-electron recombination processes.
